Extract

During the past fifty years there have been many records of the damage done by this pest to wheat and rye on the continent.

The first record in this country is by Ormerod(i) in 1882 in wheat. She says “there is good reason for believing that it was present to a serious extent before.” Since that time numerous complaints of serious damage to wheat have been recorded in various parts of the country, but the eastern counties of England and parts of Scotland have suffered most and the intensity of the attack has varied enormously from season to season.
